IMPROVEMENT IN SASH-HOLDERS.

Specification forming part of Letters Patent No. 147,726, datedFebruaiy17,1874; application filed January 28, 1874.

To all whom `t ymuy concern:

Be it known that I, AUG-Usros L. Winn NEY, ot' Harvard, in the county ofMiddlesex and State ot' Massachusetts, have invented an ImprovedSash-Supporter; and I do hereby declare that the following, taken inconnection with the drawings which aceompan y and form part ot' thisspecification, is a description ot my invention sutiicient to enablethose skilled in the art to practice it.

The invention relates to the construction of a device for supporting awiinlowsash'by fric` tional pressure., instead ot' bycountcrbalanceweights.

In lny invention I use a lon g metal case set into a slot cut for itsreception in the side bar ot' the sash, and in this case I place aframe, in which is journaled a friction-roll, this frame slidingbetween. guideways formed in the case, and being pressed forward by thestress ot' a strong sprine. W hen the case is secured in the sash slotor inortise, and the sash is placed in the window frame, the roll orframe is pressed back and held by the window-frame against the stressot' the spring, but the springpressure is such that, although the rollturns freely for the sash to be raised or lowered by pressure ot' thehand, yet it holds the sash tirnily in any position when t'ree from suchpressure.

Myinvention consists in the sash-retaining device constructed as thusgenerally described.

The drawing,` represents a construction enr bodying` my invention.

'Fig'. 2 is a sectional elevation of it.

Figure l shows the same in front view. Fig. 3 is a centralcross-section. Fig. 4 shows the roll in position to support the sash. adenotes the 111et-alca-se,to be set in a lnortise formed to receive itin the edge ot' the vertical rail ot the sash. This ease has a deepsocket, and at the central part the case is formed with guide-ribs b,between which plays a frame, c, that carries the presser-roll d, theroller turning on a pin, c, exteiiding through the frame. Back of thefranic c is a spring, f, which bears against the t'raine and tends toproject the outer side ot' the roller beyond the case. This spring maybe a lez'ttspring, as seen in the drawing, or a spring; ot" any othersuitable form or construction. The roll is held back when the sash is inplace, but is at all times pressed forward by the spring, and withsufficient stress to maintain the sash in any position, to Vwhich it maybe raised.

I claim- The sash-supporter having a r'oll journaled in a frame, c,which frame slides between guides b in a case, a., and is pressedforward by the stress of a spring, all substantially as shown anddescribed. n
